what's so great about it?
Epistar are about the best you'll get from China. Second rate if you ask me. Don't get me wrong, they do the job bit if I had the money I'd get me a KINDled unit...
any examples, i did a search with not much luck

I will have to disagree. Only because you only need 10w per sqft to veg with efficient cobs. I use only 59w for a 2x4 tent for reg veg and 36w for super veg just look at the inter-nodes on the plants under the 6500k

that's true, they produce great in veg, and you really don't need many cobs.

your picture there looks like over kill though.

36v cob x 1400ma driver = 50w output per cob. lumens per watt are near highest at this point. highest point is around 25w. In order to get the maximum efficiency you would run two fixtures the same but using a HLG-185H-C700B to drop the watts from 12-25 w. Twice as costly, but twice as efficient in lumen production meaning maximum growth. The setup I recommend gives you both 25w for low veg at high efficiency giving great inter-nodal growth, and full brightness gives 50w great for blooming. est of both. Some would go with a higher rated driver but that makes the COB less efficient but appear brighter, not better, just brighter.

i meant do you have any specs on any german leds?

Yeah but for the life of me can't find the page. They were made by geissman or something like that. Guy built a custom panel to grow the tropical plants in his aquarium. Will dig for it and post when I find it...

Lol you went to that trouble to prove a point to me :) not challenging you, just asking what that was for?
Not only that, but I've got a buddy running a k3 series Kind and it's a beast. I've ordered a k5 750.. I know 3 people personally that have had great luck with them and still run them. I'm looking forward to mine. Who cares where it's made?! Seriously, you don't think cheap shit isn't made in America... have you been to a Dollar Tree?! Lmao. There's quality and shit all over. Just because 1 in 5 people might have to get diodes fixed/replaced is not enough reason to not buy one. Also, most of the LED naysayers are just jealous, old school guys that can't afford one :) just saying! Times are changing! Just wait til the 7w and 10w tech comes out

first of all,dollar tree is full of china's crap lol. but yeah 1 in 5 kind panels have problems?thats a fuckin terrible track record like maybe as bad as mars ? if your buying a led thats only 35% efficient and costs a grand you might as well grab a lec/cmh fixture because you will be higher eff and cheaper to buy and run.

They do 10w twinchips now. Unfortunately its the same level of power running double the bulbs, so pointless really...

No no, I'm saying 1 in 5 regarding all leds.. by investing in Kind, BML, VIPARS.. you are way better than 1 in 5.. I just mean in general. Seen too many mars, galaxyhydro, etc all fail a lot.. I've not seen or heard of anyone complaining of Kind tho.

ok i thought you were suggesting kinds have a 1 in 5 rate of failure and that was good enough to take a gamble lol
